# Overview #
The equality (`==`) test in Puppet is not commutative in combination with the
undef value.
All three notices should print OR only "undef == undef" should print. Two
notices should NOT print.
<pre>
if undef == undef {
notice("undef == undef")
}
if undef == '' {
notice("undef == ''")
}
if '' == undef {
notice("'' == undef")
}
</pre>
# Actual Behavior #
Notice that undef == '' but not '' == undef.
<pre>
notice: Scope(Class[main]): undef == undef
notice: Scope(Class[main]): undef == ''
notice: Finished catalog run in 0.02 seconds
</pre>
